If under the same initial test conditions in the supposed Garden of Eden every human being would fail that test, then either, 1) God created us faulty in some way, or 2) The test was a sham. And since a fair test would mean some of us would not have sinned, then some human beings are being punished in this world for something they never would have done in the first place. This is just one of many problems that keeps me from believing.
